Abstract
Die Erfindung betrifft ein Verfahren zum dynamischen Auswuchten von umlaufenden (rotierenden), in bezug auf den Schwerpunkt symmetrischen Maschinen im zusammengebauten Zustand. Es kann bei der Herstellung und beim Betrieb dieser Maschinen Anwendung finden. Ziel der Erfindung ist die Entwicklung eines Verfahrens, bei dem das Auswuchten bei nur einer Demontage, in kuerzerer Zeit und bei verringertem Energieverbrauch erfolgt. Diese Zielstellung wird erreicht durch das Messen der effektiven Werte der Geschwindigkeit der radialen Schwingungen auf Grund der Unwucht beim Arbeiten der Maschine im Leerlauf und bei der vollzogenen Schwingungsisolierung gegen die Umgebung und durch Messen der relativen Phasen der Beschleunigung dieser Schwingungen. Die Ausgleichmassen werden fuer jede Auswuchtebene durch Division der gemessenen effektiven Werte der Geschwindigkeit durch eine Konstante berechnet, die die Maschine des jeweiligen Typs charakterisiert und zuvor bestimmt wurde. Durch Demontage der Maschine werden in den Auswuchtebenen bestimmte Ausgleichmassen unter Winkeln angebracht, die aus bestimmten relativen Phasen der Beschleunigung unter Zufuegung von 270 nach der Drehrichtung des Rotors gewonnen wurden. Die Winkel werden in bezug auf Marken auf der Welle der Maschine gemessen. Zum Auswuchten wird die Maschine an einer Feder aufgehaengt oder auf einem Vibrationspruefstand angebracht. Die radialen Schwingungen werden mit Gebern der Schwingungsbeschleunigung gemessen, deren Signal ueber einen Integrator, ein Filter, einen Verstaerker und ein anzeigendes Messgeraet zu einer Phasenvergleichsvorrichtung gelangt. Die Winkel werden mit Hilfe der gleichen Geber und eines weiteren photoelektrischen, magnetelektrischen oder elektromagnetischen Gebers bestimmt, dessen Signal ueber ein Filter, einen Verstaerker und ein anzeigendes Messgeraet zu der gleichen Phasenvergleichsvorrichtung gelangt. Fig. 1, 2The invention relates to a method for the dynamic balancing of rotating (rotating), with respect to the center of gravity symmetrical machines in the assembled state. It can be used in the manufacture and operation of these machines. The aim of the invention is the development of a method in which the balancing takes place with only one disassembly, in a shorter time and with reduced energy consumption. This objective is achieved by measuring the effective values of the velocity of the radial vibrations due to the imbalance in the operation of the machine at idle and in the completed vibration isolation against the environment and by measuring the relative phases of the acceleration of these vibrations. The balances are calculated for each balancing plane by dividing the measured effective values of velocity by a constant that characterizes the machine of that type and has been previously determined. By disassembling the machine, certain balancing masses are placed in the balancing planes at angles obtained from certain relative phases of the acceleration, with reference to 270 of the direction of rotation of the rotor. The angles are measured with respect to marks on the shaft of the machine. For balancing, the machine is suspended on a spring or mounted on a vibration test bench. The radial vibrations are measured with vibrational acceleration transmitters, the signal of which passes through an integrator, a filter, an amplifier and an indicating measuring device to a phase comparison device. The angles are determined with the aid of the same sensor and a further photoelectric, magnetoelectric or electromagnetic sensor, the signal of which passes through a filter, an amplifier and an indicating measuring device to the same phase comparison device.
